FLUID FILLED ELASTOMERIC DAMPING DEVICE

摘要

FLUID FILLED ELASTOMERIC DAMPING DEVICE A vibration bushing damping device includes an inner member and an outer member which is axially paralleled to said inner member and which encloses a substantial section of the inner member. A vibration absorbing resilient body is interposed between the inner and outer members. The body includes a first fluid holding chamber. A second fluid holding chamber is defined between the resilient body and the outer member. The second fluid chamber communicates with the first fluid chamber through a first fluid passageway. A rigid body is movably mounted in the first fluid passageway for controlling fluid flow through the first passageway to a varying extent depending on the position of the rigid body. A second fluid flow path is also provided for the fluid in the first fluid chamber.
